We have developed an efficient cascade reaction, a Suzuki−Miyaura coupling followed by an aldol condensation, for the construction of phenanthrene derivatives using microwave irradiation. For example, the reaction of methyl 2-bromophenylacetamide with 2-formylphenylboronic acid in the presence of a palladium catalyst and a base provided a biaryl intermediate, which underwent in situ cyclization to
我们已经开发出了一种有效的级联反应,一种铃木-宫浦偶合,然后进行醛醇缩合,以利用微波辐射来构建
